MIC59P50YN

Overview

The MIC59P50YN is an 8-bit parallel-input protected latched driver manufactured by Microchip Technology. It features a bipolar Darlington transistor driver for each latch, supporting high-voltage operation up to 80V and high-current output of 500mA per channel. The device operates within a supply voltage range of 5V to 12V and functions across a temperature range of -40°C to +85°C. Packaged in a 24-pin PDIP format, it integrates CMOS control circuitry for common CLEAR, STROBE, and OUTPUT ENABLE functions.

Feature Summary

• Integrates eight CMOS data latches with associated bipolar Darlington drivers for robust load switching
• Provides comprehensive fault protection including transient suppression, over-current limiting, thermal shutdown, and under-voltage lockout
• Supports split supply operation to accommodate varying logic and load voltage requirements

Applications

• Industrial automation control systems requiring high-side or low-side load driving
• Automotive peripheral interface circuits needing high current capacity
• General-purpose latch-based driver applications in embedded hardware

Procurement Notes

Verify the specific suffix 'YN' corresponds to the 24-pin PDIP package and non-RoHS compliance status as indicated in official documentation. Confirm operational parameters against the datasheet, particularly the 5V-12V logic supply range and 80V load voltage rating. Ensure environmental specifications meet the required -40°C to +85°C operating temperature range for the target application environment.

Selection Notes

Select this component when an 8-channel latched driver with high current capability (500mA) is required. It is suitable for applications needing integrated protection against electrical faults. Consider the PDIP package for through-hole mounting needs. Evaluate if the 5V-12V logic interface aligns with the system's microcontroller or logic levels.

Part Context

Part of the MIC59P50 series, which includes variants like MIC59P50BWM and MIC59P50YWM. These devices share similar functional architectures but differ in packaging and specific electrical characteristics. The MIC59P50 series is designed for parallel input latched driver applications, offering a consolidated solution for controlling multiple loads with built-in safety features.

Replacement Considerations

MIC59P50BWM and MIC59P50YWM are related parts within the same family. Verify pin compatibility and package differences before substitution. Check if the alternative variant meets the specific voltage and current requirements of the design.
